I would take one with VESA VBE 2.0 - should be on S3 Virge and Trio64. But even that quality of VESA BIOS implementation may vary from manufacturer to manufacturer - better try with some problematic games and see. All this cards should have drivers for Win9X/NT/2K and shouldn't be problem to google …

Just note setting VRAM size also don't work for me for cirrus but for std vga it works -device VGA,vgamem_mb=32 (but it has 16MB as default so not much reason to increase it)

Thanks for your attention. Damn intel! I tracked chipset datasheets and the LDRQ was removed in 1xx series. The latest with LDRQ are H/P9x and X99. Do you have an idea how to overcome this issue with your FPGA/CPLD solution? Could they use some proprietary logic for this? I very doubt.. 🙁

Where is the dedicated thread? AFAIK Win10 dropped support of ISA subsystem from the kernel so ISA card may not work there but it could work in DOS. The datasheet has better photo, from this I can read: IT8892E - PCIe to PCI Bridge F81866AD - LPC based superIO with 6x UART, LPT, FDC... F85226AD - …

I just found a new review of MSI MB with PCI & ISA slots for LGA1151 platform (H110 chipset) https://www.tomshardware.com/news/spectras-new-lga1151-motherboard-1992-pci-slots It seem's nothing surprising, just another overpriced industrial MB. I wonder if ISA DMA would work there. I was not able to …

I tried the AHCI driver with a PCIe JMB363-based card at first (my onboard SATA controller is already pretty densely populated), but wasn't very successful - the C drive was running in MS-DOS compatibility mode. It could be probably because your JMB363 card BIOS is configured in RAID mode instead …

I'm talking about true DOS mode. And it's not just games - I was able to run LLSID and listen to some .sid tunes, something that wasn't possible with OPL3LPT for some reason. And yes, SFX doesn't work, as well as C-Media's official DOS drivers. Well, did you / can you try some YMF724/744 or Vortex …

Are you talking about DOS games run under Win98 DOS window or true DOS mode? Adlib and MIDI would work - it's only I/O acces, no IRQ/DMA involved. But SFX doesn't work I expect...

Yes, SB16 with working MIDI would be fine :) Currently I use YMF724 that works for many games but still crash/hang wth some so real SB16 would be better. I already have GUS but it's very long ISA card that I cannot fit in case :) so I have it in old 486... Just one question to VGA passthrough. …

What IO range cannot be passed to LPC? I belived that all legacy IO ports that SB use can be passed by PCI2LPC bridge. I would expect more problems with DMA. LPC super IO may not be used in future, there are already some Ryzen/AMD MBs that afaik have some simplified "microIO" attached to fast SPI …

A semi-standard for LPC is TPM header but it exist at least in 2 different pin pitch and pinout may slightly differ. And it's missing LDRQ signal but there are some free pins that can be used for it (with wiring on MB). So nothing special to thing here, just use standard 2,54mm header on bridge …

My YMF724 has a pair of jumpers that routes amplified or direct signal to output jack so I can select it. In your case I guess that front speaker output is amplified and rear output is direct.

Simply say no, there was no significant progress since old good Dark Ages. I tried to explain why. All you can use is some outdated, very limited, dead port of python, JS, some perl, AWK and BASH for shellscripting. There are still living project but relative low-level to you - some BASIC, DJGPP …

Depending on what you want, there's a large number of embedded operating systems that get you even closer to the hardware with only the minimum supporting functions you require. Some even play well with legacy systems. Fancy running recent software on a VIC20 or C64? https://en.wikipedia.org/wiki/ …
